Question

Square wave generator doesn’t reproduce the signals on the screen.

(a) True

(b) False

This question was addressed to me in an interview for internship.

Origin of the question is Electronic Switch & Dual Beam Oscilloscope in section Oscilloscopes of Electrical Measurements

Answer 1

Right answer is (b) False

To explain: In a dual trace oscilloscope, the square wave generator reproduces two signals on the screen. When the switching frequency of the square wave generator is higher than that of the individual signals, the bits of each signal are provided alternately to the vertical inputs.
